Features: Double RJ45 Port: Features both vertical and horizontal RJ45 port mounting option to accommodate different device installation space requirements, with standard 8P pin for common networking cable connectors for testing and sconversion. Stable Conversion:Efficiently transfers RJ45 port 8pins to 2.54mm spaced headers/solder pad, enabling seamlessly conversion between networking ports and breadboards or wires for circuit debugging and testing. Made with 1.6mm thick, and 1.0mm mounting holes and 2.54mm spacing, ensuring compatibility with mainstream development boards and testing fixtures for easy installation and batch testing. Equipped with a metal shielding shell to minimize electromagnetic interferences, ensuring reliabled networking transmission with clean PCB traces to prevent crosstalk, for high frequency testing and data transfer. Functions as a direct networking port testing board for quick cables continuity checks, or as an extension interfaces to connection networking to microcontrollers and embedded systems, simplifying circuit connection.
